<p><span class="user-mention" data-user-id="125250">@Wesley Wiser</span> <span class="user-mention" data-user-id="116122">@simulacrum</span> so AFAIU from discussion above we should guide the submitted to use the RFC process for this change?</p>

<p>I'm honestly a bit hesitant telling a first time contributor they need to write an RFC to make a 30 line change.</p>

<p>This feels to me like the "adding a new -C flag that exposes some minor variant" situation <a href="https://rust-lang.github.io/rfcs/2904-compiler-major-change-process.html#what-are-some-examples-of-major-changes-from-the-past">called out in the MCP RFC</a>. So I think an MCP would be fine with an FCP signoff.</p>

<p><span class="user-mention" data-user-id="116083">@pnkfelix</span> Do you think we need to ask for a full RFC for this or is an MCP with FCP signoff sufficient?</p>

<p>I think if MCP is sufficient, so is an FCP on the PR itself.</p>
